TCR-5230 is temperature room curing condensed type liquid silicone rubber with two components. It showed up good characteristics,is applied to the production of brush mold handicaft industry.
Features:
1) Good fluidity
2) Excellent tensile property
3) Morderate fire resistance
4)Low hardness and high elongationt
5) Excellent tensile and tear resistance
6) Non-toxic, odorless,pass the SGS
The operating method and steps show that the great advantage of Liquid Silica Gel is that it is very simple and easy to operate, so most of the products are operated in a way, and steps are close to
1, the Liquid Silica Gel and curing agent in proportion of 100:2 by weight for Mixing Evenly
2, mixing the semi-uniform Liquid Silica Gel for vacuum treatment, so that the mold Silica Gel can be used, life module number and anti-sra performance better
3, make fixed mold frame, convenient pour glue and curing
4, Mold frame and mold surface coating release agent, easy release.
5. Place the mold in the mold frame, then slowly and smoothly pour the vacuum silicone into the mold and cover the mold inside the frame. In order to prevent the Silica Gel mold too thin can reserve the mold thickness
6, waits for the Mold Silica Gel to completely solidify, folds the mold frame, takes out the mold mold to use the scissors, the wave-shaped nozzle is convenient to turn the mold
7, the trimming Silica Gel mold burrs, the prepared Silica Gel mould can be placed in the dry blasting ventilation place for 24 hours to make the performance better

PRODUCR FILM
The turnover mold Silica Gel is mainly used in the toy gift industry, the craft gift industry, the furniture decoration and decoration industry, the character duplication, the building decoration and decoration industry, the resin handicraft industry, the unsaturated Resin Handicraft Industry, the candle craft plastic toy industry, gift Stationery Industry, Gypsum Craft Gift Industry, Mold Manufacturing Industry, glass industry products, simulation of animal and plant sculpture, Buddha sculpture crafts and other industries of product replication and mold production according to the mode of operation, if the pouring mold can choose the hardness of 20 degrees or 40 degrees of silicone, specifically: 20 degrees of hardness mold silicone features: Do Small Crafts, viscosity, good liquidity, easy to operate, easy foam, tensile tear strength, easy pouring. 40 degree hardness mold silicone features: Do Large products, viscosity, good liquidity, easy to operate, easy to bubble, tensile tear strength, easy perfusion.
Feature
1: Good Operating Performance of the turnover die.
2.Silica Gel has better fluidity, low viscosity and easy operation.
3 the smaller the shrinkage of silicone rubber, the better.
4. Silicone rubber pulls better.
5. The silicone mould can not be deformed.
6 silicone rubber hardness to be suitable for product use.
7 high temperature resistance, turnover mode number, the longer the better the service life, acid and alkali resistance aging. Preparation
method
1, a plastic bowl filled with 500g glue, at room temperature curing agent 1.5% , fully stir uniform reserve.
2. Treat and lubricate the blank of the master mould with a release agent. 3, lubricate good mother billet all round with wooden strip surround, wooden strip also apply demoulding agent processing, the gap in the middle with 2-4cm is appropriate.
4. Pour the glue slowly along a fixed filling point, and shake to remove the air.
5,60 minutes glue curing complete after four weeks and then surrounded by wood, leaving a 4cm gap, fold the log.
6, will gypsum powder 1000g water into the wooden frame, filled until the wooden frame applied plastic film is divided into two parts to facilitate mold removal.
7,20 minutes after the removal of wood, the mold is done.
Note:
1, curing agent dosage should be based on the temperature, high temperature is reduced. Too much curing agent, die will become hard brittle; too little curing agent, operation time will be prolonged.
2, in order to prevent the Mold Silica Gel physical property change, the suggestion does not add the silicon oil.
3 For the best use of your molds, store them for at least 24 hours before use.
4. Hard molds can also be made from resin.
